Sirui 100mm T1.8 Astra 1.33x AF Anamorphic Review

The Sirui 100mm T1.8 Astra 1.33x AF is an anamorphic lens aimed squarely at video creators working with full-frame or APS-C mirrorless cameras. At $849, it sits at the accessible end of the anamorphic market, offering the signature wide-aspect cinematic look with an autofocus motor, a feature typically reserved for much pricier glass. The 1.33x squeeze factor delivers a 2.39:1 aspect ratio when de-squeezed, along with the horizontal flares and oval bokeh that define anamorphic character.

The 100mm focal length positions this lens as a portrait and medium telephoto option, useful for interviews, product close-ups, and selective framing. The T1.8 aperture provides solid low-light performance and shallow depth of field, though not quite as fast as the T1.3 or T1.5 options available in higher-end anamorphic sets. Sirui has built its reputation on offering anamorphic lenses at creator-friendly prices, and the Astra 100mm continues that trajectory with autofocus integration that should appeal to solo shooters and run-and-gun workflows.
